To all whom 'it may concern.

Be it known that I, EHREGOTT T. lWINK- LER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Regulating-Valves; and I do declare the following to'be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference eing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. f A

This invention relates to regulating valves for controlling the flow of liquids; and has special reference to such valves for control- 1mg the flow of hydrous ammonia, or other refrigerating medium, from a condenser to refrigerati'ng coils.

The objects of the invention are, first, to provide a registering valve which will register or indicate u on a dial the' degree of opening of the va ve at any time; second, to provide a valve which will increase or decrease the flow uniformly for every rotation thereof. -In explanation of this I/will state that valves made with screw threads for moving the valve lengthwise by rotation, and having conical tips, do not increase or dev crease, uniformly, the flow of a liquid thereby, as the valve is opened or closed.

The above named objects are accomplished by the construction presently described, and illustrated in the accompanying drawings, in which I Figure I is a plan view of a regulating valve constructed in accordance with my invention. Fig. II is a central longitudinal section of same, with connections. Fig. III is an end elevation of the valve, omitting the operating wheel. Fig. IV is a section of the valve proper and its Seat, and Fig. V is a detail view of the valve an lesto Fig. IV.

eferring more in detail to the parts 1 designates the valve bod or valve chamber, provided with a stu ng box 2 at one end and a stuffing box 2 at the opposite end. Gland 3 is held in place by a screw cap 4, and land 5 is held in place by bolts 6 and nuts The valve rod, 8, passes through cap 4 and gland 3, and is provided with an enproper, seen at right lat, converging faces I prefer to make this tip separate from an extension 11 of threaded part 8, and to secure it thereon by a pin 12.

The valve body l is provided with a chamber 13 surrounding the part 8, and in the upper part of said chamber is a stuffing box 14 provided with a gland 15. Glands 15 and 5 are internally threaded to receive pipes 16 and 17, respectively. One end of chamber 13 has a conical seat 13', fitting the inclined shoulder 9. Concentrie with seat 13 is a reduced bore 18 which fits the valve tip 10. Beyond said bore 18 is an enlarged bore 19. i

larged screw threaded part 8. Beyond part 8 it 1s again reduced, as at 8, and has an The registering attachment comprises a .projected and threaded at 23', and threaded on said part is a pointer 28, made secure by a nut 29. The anterior face of gear 27 provides a dial, 27', which is provided with radial marks, as shown, arranged to register with the pointer 28. On the squared end 21 of the valve rod, a detachable hand wheel 30 is placed.

In a refrigerating plant, the pipej 17 leads to one of the vaporizing coils, and ipe -16 leads to a condenser, or to a manifo d supplied from the condenser. The valve thus controls the flow of liquid from the manifold or condenser to the vaporizing coil. lVhen the valve rod 8 is rotated, the rate of flow of the liquid will be increased or decreased bv the same amount at every turn of the valve rod, regardless of whether the valve passage be nearly fully, open, nearly closed, or in any intermediate posltlon. This e'ect is due to the described formation of chisel shaped valve tip 10. As pinion 20 rotates, it turns gear 25 and pinion 26;*the latter turns gear 27 which carries, the dial 27". The extent of openin of the valve will of course be indicated by the position of the dial marks, which are numbered or lettered. The valve tip 10 may be retracted l until it lieswithin the chamber 13, leaving the bore 18 wholly unobstructed. y

Having thus described m invention, what I claim as new therein an desire to secure by Letters-Patent is :-e

1. A valve body having a valve seat,- and a screw valve mounted in said body, said valve having a chisel-shaped tip, whereby the area of the valve opening will be equally varied by every equal rotative movement of the valve.

2. A valve body having avvalve seat and a cylindrical bore opening upon the seat, in

combination with a valve proper having a chisel-shaped tip adapted to rotate within said bore, said valve proper being threaded into the valve body.

3. A Vvalve body having a valve seat and a cylindrical. bore opening upon the seat,` said body having internal screw threads,- in 25 combination with a valve proper having threads engaging said threads, and having a chisel-shaped tip adapted to rotate within said bore.

In testimony whereof I affix my signa- 30 ture in presence of two witnesses.
